SIMPLY NO POWER TO THE COMPUTER
Here you first have to check the wall outlet regarding power by connecting one more device such as a radio or lamp to be sure power occurs. If the computer is attached through a surge protector, check it out.
If the wall structure out has power, what is the power cable going to the COMPUTER to see if AC voltage will make its way to the system? Do this with the use of a multimeter.
If there is power, you will have to available the PC and check out power from the power supply into the motherboard.
When using a multimeter to check voltage, be sure you use a good ground for the black color lead of the multimeter.
One main problem with an ailing Power accessory is that it may reboot a laptop computer without warning. All information is lost, and this seems to happen at the worst time.
Booting errors in the event the computer starts right up is another indicator of this ingredient going on the blink.
ELECTRIC POWER DISTRIBUTION PROBLEMS
When the power accessory begins to fail, you may be given power at one system and not another. For example, a tough Drive may receive electric power, but the CDROM Drive features nothing.

If you have a Multimeter, you can test the power supply result before purchasing a new one particular. Simply follow these methods.
Turn off the PC, smaller unplug it, and open the machine unit. Set the multimeter to read DC volts over the following range higher than 12 v. Locate a power connector similar to the hard drive or CD-ROM drive connector that is empty and turn on the COMPUTER.
You can also unplug a push connector and use it as well. Start the PC and put the BLACK probe to the power connector on one of the BLACK wires. Touch the particular RED probe to the ORANGE wire on the power charger.
The multimeter reading should be +12 volts Now affect the RED probe for the RED wire, and the looking should be +5 volts. You’ll have to affect the power supply when no or diverse readings occur. If the readings have been correct, you should check the P8 or P9 connectors on the motherboard. These connectors are often named P4 and P5. To check these connectors, execute the following…
Insert the DARK-COLORED probe into P8 from one of the BLACK wires. Put in the RED probe to the P8 connector at the REDDISH wire. The reading around the multimeter should be +5 v
Check the power going to the Mainboard connections by inserting the particular RED probe into P8 at the YELLOW wire, and you ought to get +12 volts. Next, depart the BLACK wire by pressing the black wire on the P8 connector. Check the PINK wire, and the reading could be -12 volts.
Now go the BLACK probe into the BLACK wire on the P9 connector. Test the LIGHT wire by inserting the RED probe; the examination should be -5 volts. What are RED wires on the P9 connector? You should get +5 volts on each red twine. You won’t get exactly five various or 12 volts even, so the readings will be very close, including 5. 02 volts.
If your Power Supply is a couple of v off, in either course, such as when the RED twine should be reading -5 v, but it reads -8 v, or if there are no tellings, replace the power supply.
DO NOT may help power supply from the system case when performing these checks. DO NOT perform these checks if you do not feel comfortable. Be sure to remove any static electrical build-up from your clothes and system BEFORE touching any pieces inside the system unit.
